Q

Perception

A

Interpretation of sensory information
Depend on experiences

36
Q

Transduction

A

Sensory stimulation is transformed into neural signals

37
Q

Vision

A
  1. Light enters through PUPIL
  2. Light focused by LENS into the RETINA
  3. RETINA lies in the back of the eye and contains sensory neurons
  4. RODS and CONES connect light to neural signals
38

Cones

A

3 types- one for each color
works best in bright light

39
Q

Rods

A

work well in low light

40

A
  1. Rods and Cones (retina)
  2. Bipolar cells (retina) `
  3. Ganglion cells
  4. Brain (occipital lobe)

Explains color deficiency (some aspects)
EX: those that only h

42
Q

Opponent-Process Theory

A

Color pairs:
red-green
yellow-blue
white-black
After images
Neurons in response to one member of a pair and are inhibited by the other

43
Q

Gestalt Psychology

A

the whole is different than the sum of its parts
Principles by which we organize sensory information

44
Q

Principle of Continuity

A

Able to perceive something as continuous
EX: looking at a rope

45
Q

Principle of Simplicity

A

Patterns perceived so the resulting structure is a simple as possible

46
